[PATCH v2 0/5] SGX NUMA support plus vepc reset |
Date: |

The basic SGX patches were merged into Qemu release, the left NUMA
function for SGX should be enabled. The patch1 implemented the SGX NUMA
ACPI to enable NUMA in the SGX guest. Since Libvirt need detailed host
SGX EPC sections info to decide how to allocate EPC sections for SGX NUMA
guest, the SGXEPCSection list is introduced to show detailed sections info
in the monitor or HMP interface.
This version also plus the vEPC reset support because the related kernel
patches are almost merged into kernel release, please ref below link:

Thanks!
